Overview: The GWA 2000 is a single-channel gas warning system designed by ADOS GmbH for continuous monitoring of ambient air to provide early warnings of hazardous, explosive, and non-combustible gases and vapours. It is suitable for various applications including heating systems, laboratories, and chemical industries.

Fields of Application: The system is applicable in environments such as heating systems, liquid gas storage rooms, laboratories, cold storage houses, air conditioning plants, plastic processing plants, chemical industries, and paint manufacturing plants.

Features: Key features include the use of various measurement sensors, ready, fault, and gas warning indicators, menu-aided operation via four keys, integrated buzzer, three adjustable alarm thresholds, floating alarm outputs, serial output RS 232, high reliability, low energy consumption, and easy installation.

Technical Specifications: The system supports a range of gases including hydrogen chloride, methane, neon, oxygen, petroleum spirit, propane, toluene, and xylene. It uses sensors such as infrared, semiconductor, heat reaction, thermal conductivity, and chemical sensors. Measurement ranges include CO (0-300 ppm), NO2 (0-30 ppm), CH4 (0-100% LEL), and CO2 (0-10 Vol%). The system operates within an ambient temperature range of -10°C to +45°C, with a setting time of less than 60 seconds. It features a wall-mounted installation with protection class IP 54, and outputs include RS 232 interface, alarm relays, fault relay, and analog output. The system is powered by 230 V, 50 Hz with optional voltages available.

Accessories: The system can be equipped with additional accessories such as signal horns, warning lights, warning banners, ventilation control, test meters, and plotters, depending on the system ordered.
